QtCharts causing linking errors (LNK2019)

Hi, I've been trying to use QtCharts for Qt 5.7 for VS 2013, 32 bit. However, whenever I try to use a QtChart object, for example QHorizontalStackedBarSeries, it results in numerous linking errors. Here is an example of a cpp file where this occurs:

This will also happen with other QtChart objects, such as QBarSet. Would anyone have an idea what could be causing this? I've already tried:
-cleaning the project
-in QtLauncher, cleaning the project and running QMake
-adding "QT += charts" in the .pro file

will render your program uncompilable on any platform different from windows. My advice is to stick to the standard way of including the headers, i.e. respecting their case.
Now to the main problem, have installed the QtCharts module?

Kind regards.

Even if we accept, as the basic tenet of true democracy, that one moron is equal to one genius, is it necessary to go a further step and hold that two morons are better than one genius?

You guys are on to something. Apparently I forgot to include QtCharts.lib/QtChartsd.lib in Properties -> Linker -> Input -> Additional Dependencies. I then also had to copy the QtCharts.dll and QtChartsd.dll to the release and debug folders respectively, and now my program runs. Thanks so much for your help!
